Answer:
1. Julie’s scenario doesn't match the linear function graphed, because the graphed function is f(x)=-3x+12 and must be f(x)=-5x+12
2. She has counted the slope of the line incorrect.
3. She can write f(x)=-5x+12 and draw the line with the x-intercept will be at (2.4,0) and y-intercpt ar (0,12).
Step-by-step explanation:
If Joe parked 12 miles away from the cabin and after one hour, he was still 7 miles from the cabin, then he had walked 12 - 7 = 5 miles per hour.
The initial positon of Joe is at point (0,12) (after 0 hours passed, Joe was 12 miles from the cabin). The line must pas through the point (1,7) ( after one hour, he was still 7 miles from the cabin ).
Find the slope:
So, the slope of the linear function should be -5 (not -3).
Then the equation of the function is

Answer:
y - 5 = (x - 1)
Step-by-step explanation:
Note that =
Differentiate using the power rule
(a
) = na
Given
y = x = x.
=
, then
=
When x = 1
=
. 1 =
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = and (a, b) = (1, 5), thus
y - 5 = (x - 1) ← equation of tangent
